Yes. On the super long term - wind doesn't blow, sun doesn't shine, oil doesn't flow, coal doesn't mine. Then the feasibility of nucular is a no brainer. That's all that's left besides renewables, nucular fishin. And when we run of of nucular fishin, and that day will come too... Fusion will be all that's left of the non-renewables. And it will be used surely, provided it's a net-positive delta energy.
